Claims
- 1. A method for providing a caulk, sealant, elastomeric coating, pressure sensitive adhesive, or fabric treatment comprising:a) forming an aqueous composition comprising an aqueous acrylic emulsion polymer, said polymer comprising, as copolymerized units, 70 to 99.7% by weight, based on dry polymer weight, monoethylenically unsaturated nonionic (meth)acrylic monomer and from 0.3 to 10% by weight, based on dry polymer weight, monoethylenically unsaturated acid monomer, wherein the Tg of said emulsion polymer is from −90° C. to lower than −20° C., and wherein at least 40% by weight, based on dry polymer weight, of said polymer is formed by redox polymerization in the presence of 0.0005 to 0.05 moles chain transfer agent per kg dry polymer weight; b) applying said aqueous composition to a substrate; and c) drying, or allowing to dry, said applied aqueous composition.
- 2. The method of claim 1 wherein said redox polymerization is effected in the presence of 0.00125 to 0.025 moles chain transfer agent per kg dry polymer weight.
- 3. The method of claim 1 wherein said redox polymerization is effected in the presence of 0.00125 to 0.0125 moles chain transfer agent per kg dry polymer weight.
- 4. The method of claim 1, 2, or 3 wherein said redox polymerization is effected at a pH of 4 to 8.
